AliC.8 Posted July 27, 2019 Report Share Posted July 27, 2019 I'm thinking of going to E.Fan, convwrtion on my 04 SS Silverado. I've been doing research on this and I find different things. Some say I need to get the truck tuned after, some say you dont. I know I need the fans themselves and the harness. I just need to know do I need to get a bigger radiator? Do I need to get the truck tuned after doing the installation? Someone, Anyone. PLEASE HELP!! Quote Link to comment Share on other sites More sharing options...
drumminovertime Posted July 29, 2019 Report Share Posted July 29, 2019 You will have to have someone program the ecu to enable the electric fan control. anyone with hptuners should be capable of this. I just did it on my 03, and mine already had the larger 34" inch radiator. Measure your radiator, if its 28" wide, you need the bigger one, if that's the case, just order a radiator for an 05-06 silverado Quote Link to comment Share on other sites More sharing options...

So it's just fans,harness and tune? Quote Link to comment Share on other sites More sharing options...
drumminovertime Posted August 1, 2019 Report Share Posted August 1, 2019 I used an aftermarket fan from 1-800-radiator. Correct, fans, harness, and I have HPTuners so I was able to enable them in the pcm myself Quote Link to comment Share on other sites More sharing options...

Yeah you have to enable them and set on/off temps/air condtioning on/off pressures. Pretty straightforward Quote Link to comment Share on other sites More sharing options...
